The Spurs returned to the AT&T Center Saturday night, but something was amiss.

Fans appeared torn between excitement for the return of hoops and a fierce longing for No. 21.

Down on the court, it was a new 7-footer named Pau Gasol taking the jump. The man who had done it for the past 19 years was off somewhere watching the game or working at his speed shop or maybe dabbling in both.

Life without Tim Duncan has begun, whether fans are ready for it or not. Judging by their Twitter posts, most fall into the latter category.

Browse through the gallery above to see what life without Duncan looks life.
